' Letters Patmt No. 90,829, dated June 1, 1869.

IMPROVEMENT IN WAGON-BRAKES.

The Schedule referred to in these Letters Patent and making part of the same.

To allwhom it may concern- Be it known that we, WILLIAM R. ENGLISH and STEPHEN ROGERS, of English Centre, in the county of Lycoming, and in the State of Pennsylvania, have invented certain new and useful Improvements in Brakes for Vehicles and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of our invention consists in the construction and general arrangement of a self-acting brake Figures 2 and-3 show the manner of securing the tongue so as to operate the brake.

A A represent the hind wheels, on which the brake is to operate.

13 B are the rear hounds, which are connected at their front ends by metal plates, on their upper and rear sides, forming a box, 0, through which the perchpole D- passes.

To the upper side of the perch-pole, a suitable distance in front of the rear bolster E, are pivoted the inner ends of two levers, F F, the outer ends of which are placed in socketsG G, one at each end of the rear bolster E.

The levers F F are connected, by means of rods I I,

l to the brakebar H, laid across the perch-pole and hounds, in front of the wheels AA, and held in position by means of a bent bar, J, the ends of which are secured to the perch-pole, and laid over the brake-bar, as shown in fig. 1.

When the perch-pole D is, in the manner hereinafter to be described, moved backward by theteam backing up, the inner ends of the levers F 1* are moved toward "the rear, which, by the means of the connect; ing-bars I I, also moves the brake-bar H backward sutficiently to allow the brake-blocks to act on the wheels.

As soon as the team commences to draw again, by the exact reverse motion, the brake-blocks are carried away from the wheels.

The front end of the perch-pole D is provided, on the upper side, with a plate, or bar, a, which projects onlya short distance beyond the end of the pole.

This plate, or bar a, has a curved slot vertically through it, just beyond the end of the pole, as seen in fi 1.

-Tlie under side of the perch-pole I), at the front end, is also provided with a similar, but larger plate, or

bar, b.

This plate extends farther beyond the end of the pole, and is also provided with a curved slot exactly underneath and corresponding in size with the slot in the plate a.

In addition to this curved slot, the plate I) is also slotted longitudinally, for the purpose of securing the perch-pole D to the front axle, which is done-by a pin,

a, passing through the front bolster, bed, and axle, and also passes through the longitudinal slot in the plate b.

Between the plates a and b is inserted another plate, 11, the rear end of which is provided with a pin, e, projecting both above and below said plate.

The pin 0 is inserted in the curved'slots on the plates at and b.

The plate (I has also a round hole, through which the pin 0 passes, and a slot extending forward from said hole.

The fiont end of the plate (1 forms two arms, f f,--

between which the rear end of the tongue L is placed. A pin, 7:, passes through the front hounds O O, the arms h h, and the tongue L, thus securing the tongue to the wagon, and also connecting itwith the perch- I pole.

The ends of the front hounds O O are slotted-where the pin it passes through, so as to allow sufficient backward-and-forward motion of the tongue.

. The operation of our brake is very simple. For instance, when the wagon is going down hill, the team, of course, bears back on the tongue.

The slots in the front hounds O 0 allow the tongue tomove a certain distance backward, which also moves the plate (Z in the same direction.

This plate, by means of the pin 6, in the curved slots of the plates a and b, carries the perch-pole D backward also, which, as already described, applies the brakes to the wheels.

In the metallic box 0, through which the perch-pole D passes, we place a pin, m, operated by a lever, a, and held outward by a spring, 0, for the purpose of preventing the brake to be applied, if so desired.

By turning the lever -n,'the pin or is moved inward into a hole, or recess in the side of the perch-pole, which, of course, will prevent the pole. from moving backward, and, consequently, not acting on the brake.

Having thus fully described our invention,-

What we claim as new, and desire to secure by Letters Patent, is

1. The arrangement of the perch-pole D, levers F F, rods I I, brake-bar H, and bar J, in combination with the box 0, pin m, and lever n, with spriug 0, all constructed and operating substantially as herein specified. v

2. The arrangement of the perch-pole 1), plates, or bars a b (1, pin 0, arms ff, tongue L, and slotted hounds O 0, all substantially as and for the purposes herein set forth. 7

In testimony that we claim the foregoing, we have hereunto set our hands, this 30th day of January, 1869.
